WATER-CLOSET.

Specification of Letters Patent.

Patented sept. 23, 1919.

Application filed April 15, 1918. Serial No. 228,535.

To all whom t may concern:

r Be it known that I, EARL G. WATRoUs, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Water-Closets, of whichthe following is a specification.

My invention provides a water closet constructed for special service,beyond its ordinary utility, in the cleansing of sanltation receptaclessuch as bed pans, and it consists in the features of construction andcombination and arrangement of parts hereinafter more fully describedand as specified in the claims.

It has heretofore been suggested by others that a closet be formed witha bowl of plan area adequate to accommodate a bed-pan and that,supplementally to the usual flushing equipment, a central water-jetarrangement be provided for projecting a stream upwardly into theinverted bed-pan placed in the bowl, but my invention affordsimprovement in many important respects over such closets as heretoforeproposed.

In the drawings Figure 1 is a plan view of a closet constituting anembodiment of my invention; Fig. 2 is a section partly in elevationtaken longitudinally therethrough; Fig. 3 is a cross section on line3--3 of Fig. 2, and Fig. 4 is a side elevation.

The principal closet fitting, generally indicated at 10, is preferablyan integral structure and may be of any desired type affording asuitable normal flushing channel 11, that is connected with the sourceof water supply typified by piping stud 12 and a suitable eductionpassage, preferably for siphonic action. The features of bowlconstruction and auxiliary water supply that constitute my improvementshave no especial relation to the operating type (si honic or otherwise)of the closet except t at, as is customary, the eduction passages shouldbe so arranged as to maintain a definite water level in the bowl. Thecloset fittinoin cludes a specially shaped bowl 13 in willich a normalwater level as indicated by line WL is maintained, and the inner surfaceof the bowl affords shoulders 15, above the normal water level, local tothe forward portions of the opposite sides so as to leave free fromobstruction an I-shaped watercontainin zone or area that comprises acentral orward zone 16 extending full length of the bowl and atransverse rear pital service, the whole bowl and-its shoula ders may bespecially designed to receive the particular size of bed-pan B that isadopted as standard.I Each of the supporting shoulders is apertured asat 18, ynear its rear end, these apertures being diago-- nallypositioned, suitably to throw water jets upwardly and convcrgently; andwater supply means, independent of the normal flushing equipment, isprovided for such jet openings. In the specific construction shown, anddesirably employed, the closet fitting is molded with its bowl 13 havinga relatively shallow forward end (Fig. 2) centrally deep enough toai'ord a quiteshallow water-channel 16, and the sides of this channelmerge through smooth curves into the portions that form the shoulders15. At about the rear ends of the shoul-l ders 15 the bowl-bottomdescends in smooth curves, tapering` downwardly as at 20, to communicatewith the usual eduction passages. Conforming with the under walls of thebowl I provide a channel 21, formed between the bowl walls and a web 22that curves across the under-side of zone 16 and rearwardly along theunder curve of zone 17, this web having an inlet openin 24communicating, through suitable fittings, with the auxiliary supply pipe25 controlled by handle 26, so that water may be delivered to jets 18.

It will be apparent that when the customary seat (not shown) is down,the closet serves all its ordinary uses, (the shoulders 15 beinglocalized to normally non-receptive portions of the bowl) and that theflushing of the closet through the customary rim channel 11 willsufficiently cleanse al1 of its surfaces, the auxiliary water supplydevices not being ordinarily called into play. With the seat raised thebed-pan B may be placed upsidedown to rest, above the normal waterlevel, on the shoulders 15 with its opening above the opposed diagonaljet orifces 18, so that when water is admitted from the auxiliary supplypipe 25 it is projected upwardly in convergent streams to meet,preferably, at about the opening of bed-pan and consequently to spread,fan-shaped, lengthwise of the pan thoroughly cleansing its innersurfaces.U By the arrangement described the many disadvantagesofaCentral jet are avoided and an 'eiiicient water-de" livery arrangementis provided thatidoes not interfere with such provision of water-`001L1-taining zones asi-will `fully Satisfy-non.
